1. What is the water cycle?
The water cycle is a continuous process in which the water moves through the environment, driven by the sun's source of energy.
2. Does the water cycle have a beginning or end?
The water cycle does not have a start or an end because it is an ongoing process.
3. Starting with a puddle on a sunny day, describe how water might move through the water cycle and eventually fall back as rain.
A puddle on a sunny day may move through the water cycle by evaporation, condensation, and then the water falls as precipitation. The sun will also help with this process because the sun is energy for the water cycle to occur. First the puddle will evaporate into the air. Then it will condensate into a cloud. Finally it will fall as precipitation.
